Oiling modifications

well in the oil mod guide it shows him drilling thru the oil galleys...

one thing he is doing is slightly enlarging them but also removing any burs that hinder flow...

but if you make it flow to much to the top end you are starving everything else...

and what bolt are you talking about??



"with the cam side main bolt / stud installed."

This is the one I was talking about !Also,is it just this one galley that would be drilled,or is it at all the mains ?? I know I sound like I'm asking dumb questions,but I'm getting closer to actually doing all the work and I don't want to screw it up !!
